OOPs PHP!

As we struggle with php this week, I thought I would make the situation little more daunting. As if the current situation, with php tutorial and network project deliverable, is not enough challenging!

So if anybody wants to learn OOP way of php, here is good tutorial from nettuts.
I couldn't agree more when the author compares relationship between blue-print/house to class/object. The article is worth the reading, especially if you consider yourself a geek. I didn't read it all, so technically I am not a complete geek yet.

I think the author is correct when he opines that "... OOP is actually a very straightforward and ultimately simpler approach to programming."

RSS Advisory Board
